The prince and the primatologist discussed the environment, slowing down climate change, and not having too many children in the article, which is peppered with photos of the two smiling at each other.

“What we need to remind everybody is: These are things that are happening now,” Harry said of climate change and the finite resources that we have left on earth. “We are already living in it. We are the frog in the water and it’s already been brought to the boil. Which is terrifying.”

Goodall pointed out that climate change was indeed “terrifying,” perhaps even more so to Harry now that he and Meghan have brought a child into the world. Their son, Archie Harrison Mountbatten-Windsor, was born in May.

When Harry spoke about how he had wanted to preserve nature for future generations and his own children, even before he became a father, Goodall joked that hopefully he didn’t want “too many” kids.

“Two, maximum!” the royal replied — meaning Archie might have a little sibling in the next few years. Goodall herself has one child, a son named Hugo Eric Louis van Lawick.
